FIRE-ARM.

SPECIFICATION' forming part of Letters Patent No. 291,153, dated January 1, 1884. Application lcd March 17, 1883. (Model.)

fo all whom may concern:

Beit known that I, DM'ID S. COLE, ofCol u mbus Junction, in the county of Louisa and State of Iowa, have invented certain new and useful Improvements in Ireech-Loading Fire-Arms; and I do hereby declare the following to be a full, clear, and exact description of the invcn tion, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in breech-loading fire-arms; and it consists, first, in a breech-block having a rearward extension 0n its rear upper end for the purpose of forcing the hammer back to full^cock when the block is depressed; second, in a hammer having its front edge so formed that after it has been forced back to full-cock by the extension on the breeclrblock the block will continue to descend for the purpose of operating` the cartridge-extractor, third, in a cartridgeextractor extending forward to and turning upon the same pin or bolt as the operating-lever; fourth, in the arrangement and combination of parts, which will be more fully described hereinafter.

Figure lis a side elevation of my invention, partly in section, showing the different parts in position. Fig. 2 is a similar view, showing the parts open. Fig. 3 is a perspective of the breech-block, taken from its front side.

A represents the receiver, and B the barrel, which is connected thereto. Cut vertically through this receiver is an opening, C, large enough to allow the breech-block D to play vertically up and down and the cartridge-ex tractor to move back and forth. rlhe breechblock has a suitable groove, E, formed .in the upper end of its face, so that it will move up over the end of the cartridge without striking it in such a way as to endanger a premature explosion. 'The lower end of this block is divided into two prongs, so as to straddle over the extension G, which is formed upon the operating-lever, and one of these prongs is cut a ay upon its front side, so as to form the shoulder H, for operating the cartridge-extractor. rlhis shoulder will be located at such a point that the breech-block will be given a suitable amount of vertical play without operating the extractor, unless it should be desired to do so. Upon the rear upper` corner of the breech-block is formed the extension L, which may either be of the shape here shown or any other that may be preferred, and which is intended to operate the hammer N for the purpose of coeking it when the breech-block is depressed. As the under side of this depression is curved, as it strikes against the upper corner of the hammer, which is soembedded that it cannot well be operated by the finger, the hammer is forced backward either to a full or a half cock, according to the distance the breech-block is moved. 'W hen it is desired to full-cock the hammer, the operatinglever is moved just far enough to force the hammer back to the second notch. XVhen the breeclrblock is depressed by means of the operating-lever its full distance, it full-cocks the hammer, and at the same time operates the cartridge-extractor. \Vhcn the breech-block is returned to place by this lever, the hammer is at full-cock and the gun is again ready for use, the cartridge having been inserted. In case it should be desired to uneoek the hammer, the breech-block will be depressed a suitable distance, the trigger held back, and then as the breech-block is again raised into position the hammer will move forward to the first notch, or will become entirely uncooked if the trigger is not released.

The cartridge-extractor K is of the form shown. and rests against the same axle, I, as the operating-lever. rlhe pivotal point or extension of the extractor is made to extend forward as far as possible, so as to give the breech block as much ot' a leverage as possible when it strikes the shoulder .T upon the lower cor ner of the extractor', and thus give both a powerful and a quick movement for the purpose of ejecting the shell clear from the receiver.

The upper end of the hammer is inclined, as shown, so that the extension on the breechblock will force the hammer backward with as little friction as possible. Then the extension on the breech-block reaches the point 1, the hammer is back to full-cock, and then as the block continues to descend to operate the cartridge-extractor the extension moves down in front of the vertical edge 2, as shown in Fig. 2. The lower end of the hammer forms the stop which prevents the block from moving any farther downward.

rlhe operating-lever, which is piv oted to the breech-block, has its front end slotted, as shown, and catches over the pivotal axle against which the cartridge-extractor rests. Vhen the breech-block is depressed to its full extent, it is only necessary to knock out the pivotal pin which connects the lever and the block together, and then the operating-lever, the breech-block, and eartridgeextractor can be removed Without removing any other part. In order to cause the lever to close entirely or to open entirely after it has been moved to a certain point, a suitable spring, I), is secured to the under side of the barrel and extends backward, so as to bear against the top side ol' the front end of the lever. The pressure of this spring assists in opening and closing the lever after it has reached a certain point.

Having thus described my invention, I claim- 1. In breech-loading fire-arms, the combination of a vertically-moving breeelrblock, D, provided with an extension, L, upon its npper rear corner, the operatinglever, which is connected directly to the breech-block, and the hammer N, having a straight surface, 1, and the recess 2, formed on its front edge, substantially as shown.

2. In a breech-loading fire-arm, the combination of a single pivotal pin, I, the cartridgeextractor K, and the operatin g-lev er having an open-ended slot in its front end, and the vertically-moving breech-block l), which is pivoted to the operating-lever, whereby when the pin which connects the lever and the breechblock together is removed the lever, the cartridge-extractor, and thc breech-block can all be removed from the gun, substantially as 3. The combination of a breech-block having the extension formed upon its rear side to operate the hammer, and provided with a shoulder, with a cartridge-extractorwhich has a shoulder formed upon its lower rear corner for the breech-block to strike against, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
